Plant mediated bio synthesis of silver nanoparticles: Characterization and antimicrobial activity

Abstract

The silver nanoparticles (AgNPs) have gained attraction of Chemist and Physic’s since last decade and widely accepted in electronics, engineering, nanotechnology, biotechnology, medicine and chemical industries. The green synthesis of silver nanoparticles has been known for their beneficial, eco friendly and less hazardous results as compared to other conventional methods. Based on the literature survey, here we first time report the synthesis and bioactive analysis of (AgNPs) by aqueous extract of leafs of variety of medicinally important plant belonging from family Cupressaceae. During the study, multiple changed was observed for different part of different plants, an intense surface resonance Plasmon band in the UV-visible region at 465 nm. The further studies of formation of AgNPs were confirmed by UV, FTIR, SEM and antimicrobial activity.
